MEANS FOR SECURING coveas UPON CANS.

SPECIFICATION forming part of Letters Patent No. 259,800, dated June 20,1882, Application fil ed March 18, 1882. (Model.)

To all whom 2t may concern:

Be it known that I, EPAMENONDUS BOTTEN- BERG, of Astoria, in the countyof Fulton and State of Illinois, have invented a new and Improved Meansfor Securing Covers upon Cans, of which the following is a full, clear,and exact description.

The invention consists in combining parts for holding the cover to thecan, as hereinaf-- ter described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of my new and improved fruit-can as itappears when sealed.

7 Fig. 2 is a plan view of the same, one of the attachment hooks orwires being removed and Fig. 3is a sectional elevation of the can, takenon the line no a; of Fig. 2, and a side elevation of the tool, showingitin full lines in position for sealing the can and in dotted lines inposition for unsealing the can.

A represents the fruit-can, which is formed with the head or flange d. Bis the cover of the can. 0 represents a ring of rubber placed betweenthe cover and the top of the can. D is the spring-plate. E representsthe attachment hooks or wires, of which there may be two, three, ormore, according to the form of the spring-plate; and F represents thetool for sealing and unsealing the can.

The cover B is by preference formed with a flange adapted to fit insideof the can, and is formed with the central upward projection, c, asshown in Fig. 3.

The spring-plate D is formed with the three arms f f f, which are ofsuch a length relative to the size of the cover as to reach a littlepast the cover when the plate is placed centrally upon the cover, asshown, and the ends of the arms are slightly upturned to form the lips'i, and slightly cut away at the sides, near the said lips, as shown ate e in Fig. 2, to receive and holdthe attachment hooks or wires EL; andthe plate is formed with the central depression, a, made from the underside of the plate,which forms the bearing-point of the plate upon theupward projection c of the cover, as shown clearly in Fig. 3.

The attach ment-hooks E are preferably made of wire bent to form theloops h, which fit over the lips c" and in the cut-away places 0 e ofthearms, and to form the diverging portions ij,

which are bent at the ends to form the books is k, which are adapted tocatch under the flange d for sealing the can.

The tool F is formed of the levers g g, pivoted together toact likepinchers, by the pivot l. The end of the lever g is formed with theplain projection or lip 10, adapted to catch under the flange 01 of thecan, while the end of the lever g is undercut to form the pointed head1), and

the outer edge ofthis' head is outwardly curved,

tylre, the toolF is applied, the plain hook p being placed under theflange of the can, and the undercut hook p placed'over the lip t andover the loop hot' the attachment-wire, as

shown in full lines in Fig. 3. Now, upon applying power to. the levers gg the tool not only serves as an easy means of bringing the plate Dforcibly upon the cover B, causing it to hermetically seal the can, butat the same timesprings the plate, andthe hook 19' has a cam action upontheloop h of the attachmentwire, and automatically forces the hooks k kof the wires into'engagement with the flange d of the can.

To unseal the can the tool F is applied, as shown in dotted lines inFig. 3, with the point of the head p! placed upon the lip t in front ofthe loop h, instead of over it, as in the case of sealing the can, asjust described. With the tachment-wires to be automatically disengaged 1e0 from the flange d of the can and permit the removal of the cover, aswill be clearly understood from Fig. 3.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The plate-attachment hooks E and the canhaving flange d, in combination with the cover B, having a centralupward projection, as and for the purpose specified.

2. The plate D, formed with the lips i, in combination with theattachment-wires E,

formed with the loops h and hooks 7c 70, substantially as described.

3, In a hermetically-scaling frnitcan, the 15 cover B, plate D, loopedand hooked attachment-wires E, packing C, and projection d on the bodyof the can, constructed and combined for joint operation substantiallyas shown and described.
